Admob Fillrate = 0

i'm using admob for an app i just launched the other day, at first there were no downloads, but with a campaign i'm using now, i've gotten 140 requests yesterday and as of now, 44

Solution 1:

You have a very low number of requests. So any data should be treated with a pinch of salt. Having a fill rate of 0% just means that there have been no ads available for your app for those 299 requests.

As you get a wider coverage you will get better fill rate.

You can also improve your fill rate by using a mediator.
